Additional Note: The MR44 is a Mercuric-Oxide cell of the same dimensions as the L1154. The MR55 cells are no longer manufactured because of their toxicity. If your requirement is to replace an MR44, you may consider using the Alkaline L1154 in its place.Vinnic 357 Watch BatteryLR44 AG13 L1154Alkaline10 pack1.5V
